“…These results support the earlier studies, which also found positive effects of raw and composted de-inking sludges on soil microbial biomass and enzyme activities (Simard et al 1998bChantigny et al 2000;Gagnon et al 2000). In our study, neither acid nor alkaline phosphatase activity was significantly (r = 0.15 -0.19, P > 0.05) correlated to Mehlich-3 extractable soil P content.…”

Baziramakenga, R., Simard, R. R. and Lalande, R. 2001. Effect of de-inking paper sludge compost application on soil chemical and biological properties. Can. J. Soil Sci. 81: 561-575. A 2-yr field study evaluated the effect of applying compost of deinking paper residues and poultry manure (DSPC) on the chemical and biological properties of Tilly silt loam (Gleyed Humo-Ferric Podzol) in Sainte-Croix de Lotbinière, Québec, Canada. The experiment began in 1996 with snap bean (Phaseolus vulgaris L. 'Centralia') and continued in 1997 on the same plots with potato (Solanum tuberosum L. 'Gold Rush'). In 1996, treatments included three rates of mineral fertilizer (MF) (60, 120 and 180 kg P 2 O 5 -K 2 O ha -1 ), three rates of DSPC (14, 28 and 42 Mg ha -1 on a dry matter basis) alone or in combination with MF, and an untreated control. In the spring of 1997, main plots were divided into four subplots and P fertilizer was applied at 0, 44, 88 and 132 kg ha -1 . The DSPC increased soil pH and water content. Soil inorganic N increased just after DSPC application, but this effect lasted only 1 yr. Soil Mehlich-3 extractable P showed a significant increase due to DSPC application and the increase was much larger when DSPC was applied in combination with P fertilizer. Soil phosphatase and urease activities were also increased by DSPC. Application of DSPC increased soil Mehlich-3 extractable K and Mg contents. Except for Mn and Zn, soil Mehlich-3 extractable heavy metal contents were not influenced by DSPC. This experiment indicates that compost derived from a mixture of de-inking papermill sludges and poultry manure is a potential source of nutrients for crops and can effectively improve chemical and biological properties of low fertility or degraded soils.

“…For example, incorporation of a combined sludge at 246 Mg ha -1 , having a water holding capacity of 0.19 and 0.12 cm 3 cm -3 at -33 and -1500 kPa, increased soil water 20 and 74% at -33 and -1500 kPa, respectively (Zhang et al 1993). Soil water contents of a silty clay loam and a clay loam were increased by 50 and 100 Mg ha -1 deinking sludge from 271 to 726 d after sludge application, compared with the unamended control (Chantigny et al 2000a). Increased total soil water may create more favorable conditions for soil organisms, particularly during drought (Chantigny et al 2000a).…”

“…Microbial biomass, CO 2 evolution, and the activity of several enzymes (fluorescein diacetate, acid phosphatase, arylsulfatase, and urease) were increased 11 mo after application of raw sludge with a C:N ratio of 109:1 to a Fredericton sandy loam (Gagnon et al 2001). Soil amended with deinking sludge at 50 Mg ha -1 , compared with an unamended control, had increased microbial biomass C, hydrolysis of fluorescein diacetate, and alkaline phosphatase activity (Chantigny et al 2000a). Application of a paper mill/swine manure compost at 11.5 Mg ha -1 to a sandy soil increased microbial biomass C and the activity of several enzymes by 55% and 30% .…”

Pulp and paper mill sludges are produced from primary and secondary treatment of wastes derived from virgin wood fiber sources, recycled paper products, and non-wood fibers. Sludges and sludge composts may be utilized in agriculture to increase soil organic matter, improve soil physical properties, provide nutrients, and increase soil pH. Positive effects of primary, deinking, and low-nutrient combined sludges on soil quality are primarily due to increased soil organic matter, aggregation, water holding capacity, infiltration rate, and cation exchange capacity. Nitrogen and P immobilization are often induced by primary and deinking sludges, but can be overcome by delayed planting, adding N and P, planting of legumes, or composting. Improved crop production obtained with secondary treatment sludges is most often attributable to enhanced nutrient availability, particularly N, but improved soil physical properties are implicated in some studies. Pulp and paper mill sludges and sludge composts are useful soil amendments and plant nutrient sources. Key words: Paper mill sludge, soil physical properties, N and P immobilization, nutrient efficiency, land application

“…Organic matter is involved in the enhancement of soil quality since it acts on soil structure, nutrient storage and biological activity [2] . The application of organic fractions of urban wastes (e.g., sewage sludge and municipal solid wastes) as organic amendments to agricultural soils of these areas may be of use in improving their quality and be considered an attempt to alleviate the serious environmental and health problems caused by their accumulation [3] . Aggregation and Soil Organic Carbon (SOC) concentrations represent integrative effects of soil type, environment and soil management practices including crop rotation, tillage and fertilizer management [4] .…”

Problem statement: Distribution pattern of enzyme activities in soil aggregate size classes as affected by organic amendments is not well understood. Approach: A study was conducted to evaluate the effects of repeated annual application of Cow Manure (CM), Sewage Sludge (SS) and Municipal Solid Waste Compost (MSW) on the distribution of β-Glucosidase (βG) activity within aggregates of a soil. Soil samples were collected from 0-15 cm of a soil which, had been treated annually from 1999-2006 at 4 application rates with three replications. A control (with no application) was also run. Soil organic C content and βG activity were measured in 5 aggregate size fractions. Results: Results illustrated that application of the amendments decreased the proportion of microaggregates (<0.25 mm). The proportion ranged from 64% in control to 35% in MSW. In contrast, the proportion of macroaggregates (>0.25 mm diameter) enhanced from 35% in control to 65% in MSW. Application of organic amendments modified the distribution of Soil Organic C (SOC) content and βG activity. Distribution of SOC in macroaggregate classes was not identical in CM, SS and MSW treatments. The distribution pattern of βG activities in aggregate size classes was dissimilar to those of SOC contents. In general, an increasing trend was observed in βG activity as the aggregate sizes increased. The highest level of βG activity was observed in aggregate size classes of >2 mm of all applied soils. Among the solid waste treatments, CM induced greater βG activity in macroaggregates. For all aggregate size classes, the lowest level of βG activity was observed in control. Conclusion/Recommendations: To conclude, organic fertilization increased the proportion of macroaggregates to microaggregates. The highest activities of βG and SOC contents were observed in macroaggregates and in soils received the highest rates of organic fertilizer applications.
